Title: Swing-open extruder head for extruders
Inventor: GERLOFF KLAUS DIPL ING
IPC: B29C48/05
Filed: 1984-06-27
Abstract: The application relates to openable extruder heads on extruders for thermoplastic and heat-curable compositions, in which according to the main patent the head parts which are pivotable about fixed fulcrums are supported against the extruder head as resiliently flexible intermediate members by means of pressure medium cylinders directly attached to them. According to the invention the pressure medium cylinders are shielded against undesired effects of thermal convection by thermal insulation attached to the head parts. It is thus possible to eliminate the hitherto constant danger of malfunctions resulting from the formation of vapour bubbles in the hydraulic fluid.

Patent DE-3432837-A1 (DE)
Inventor: SCHEFFLER PETER DR PHIL
IPC: H03M7/48
Filed: 1984-09-06
Abstract: A data compression system (1) for the transfer of data has a register (15) for recording a unit of information from input data, a conversion system for transforming the data and an output (25) for the transformed data, as well as a control system (4, 5). In order to be able to undertake data compression without loss of information, the invention includes a comparator linked with the output of the register (15), and a counter (16) controlled by the comparator. The comparator (17) checks all the data of the information unit, and the control system (4, 5) is so designed that in the event of non-uniformity the content of the register (15) is fed to the output (25) and in the event of uniformity, a marker bit is produced and the counter (16) is advanced by one position, and the counter status is fed, together with the marker bit, to the output (25) if two successive information units do not agree. An associated data expansion system (2) contains the output data of the compressor (1), checks the marker bit and conveys an information unit which has no corresponding marker bit, to its output; on the other hand if a corresponding marker bit is present the information unit is fed into a counter and an information unit whose data are mutually identical and possess a predetermined value is fed to the output, with simultaneous advancing of the counter (16) each time by one position, as many times as is necessary until the counter status acquires a predetermined value.

Title: Rollable chair with blocking mechanism
Inventor: JASPERS HERMANN
IPC: B60B33/02
Filed: 1984-11-24
Abstract: The invention consists of a vertically adjustable chair, whose two runners are provided in each case with 2 rollers. Said rollers are blocked in their position in the basic position of an unblocking bar.   If the unblocking bar is moved towards the rear, a turning and sliding joint is actuated at the same time. The latter consists of two pieces of flat material, which are parallel to one another and are welded firmly in the runners on the ends of the bar, and rods which are connected to said pieces of flat material in an articulated manner, are removed from the rollers when the unblocking bar is actuated and thus set the chair into readiness for rolling. After release of the unblocking bar, the blocking of all four rollers is reinstated immediately by spring action on the bar.

Title: Nozzle and mixing device with nozzle
Inventor: HALL ADRIAN BOONE
IPC: B29C39/00
Filed: 1985-01-28
Abstract: A flow-directing nozzle device (10) is provided which produces a turbulent flow of a fluid charged with filler in order to prevent or to reduce the separation of the filler (for example glass fibres) from the fluid during the recirculation flow of the fluid in the mixing head of a reaction injection moulding device for injection moulding plastic objects. The nozzle (10) has an inner, flow-directing element (30) which defines for the fluid charged with filler a flow path folded through 180 DEG , as a result of which a turbulent flow is produced inside the nozzle (10) of the mixing head of a reaction injection moulding device. A mixing head device with the aforesaid nozzle (10) for a reaction injection moulding device is provided in particular for use with reactive fluids charged with fillers for producing plastic objects. In the mixing head device, a separation of the filler material from the reactive fluid is prevented or reduced in that the fluid charged with filler is recirculated throughout the mixing head by means of turbulent flow, as a result of which blockage of the openings of the mixing chamber of the mixing head is also prevented or reduced. <IMAGE>

Title: Process for treating an aqueous solution containing iron chloride and hydrochloric acid
Inventor: HEINZ ERNST DIPL ING
IPC: C23G1/36
Filed: 1985-06-15
Abstract: The aqueous solution contains from 10 to 30% by weight of iron chloride and from 15 to 25% by weight of hydrochloric acid. The solution is mixed, wholly or partially, with concentrated HCl gas in a crystallization zone at temperatures of from approximately 20 to 60 DEG C, and as a result a concentrated solution is generated which contains crystallized iron chloride and comprises at least 30% strength hydrochloric acid. A first separation device is employed to extract therefrom a salt slurry containing crystallized iron chloride and hydrochloric acid having an HCl content of at least 30% by weight. The remainder of the aqueous solution to be treated is mixed, in an evaporation zone, with flue gas which contains HCl gas and has temperatures of from 750 to 950 DEG C. The flue gas originates from a thermal dissociation process. From the evaporation zone, an HCl-containing gas phase and a liquid phase are drawn off separately. Concentrated HCl gas is extracted from the HCl-containing gas phase and is passed into the crystallization zone. The liquid phase is mixed with the salt slurry from the first separation device, the mixture being separated into a concentrated salt slurry and a liquid phase. The concentrated salt slurry is fed to the thermal dissociation process and the liquid phase is fed to the evaporation zone.

Abstract: A method for feeding a metered quantity of fuel to an internal combustion engine is described. The fuel is metered in a chamber, which may have the shape of a line, the metered quantity being varied according to the engine load. A pulse of a gas, for example air, is fed into the chamber in order to expel the fuel from the chamber and feed it to the engine by way of a nozzle. The quantity and/or the length of time in which the gas is fed into the chamber is varied as a function of the changes in the metered quantity of fuel.

Title: Clear-view screen
Inventor: REINHARD HEINRICH
IPC: B23Q11/08
Filed: 1985-09-11
Abstract: A clear-view screen contains a tubular cylindrical housing, the outer peripheral surface of which carries an annular flange and a thrust ring with which the housing is to be fastened to an appropriate wall. Both front ends are closed by window panes, of which one is inserted in a firmly sealed-off manner, while the other is mounted on the spindle of a drive motor in such a way as to be fixed in terms of rotation and is sealed off from the housing by means of a labyrinth seal. To be able to observe operations in closed work spaces in an operationally safe manner and with little effort, for example in closed work spaces of an automatic machine tool, the drive motor is arranged in the intermediate space between the two window panes, while its feed lines pass in a sealed-off manner through the wall of the tubular housing.

Title: Analysis and detection method for encryption codes of television transmissions and device for carrying out the method
Inventor: ZBERG FRANCOIS J
IPC: H04N7/169
Filed: 1986-01-08
Abstract: An automatic analysis and detection method consists in successively testing each of the different possible encryption codes with the analysis for each of these codes of a number of fields which were supplied by an adapted decoder (30) operating on the basis of this code. The analysis comprises the determination of the subtraction of the image information items from two adjoining lines of the same field; the subtraction signal is investigated for the presence of signals, the frequencies of which are characteristic of displacements. The analysis is done for each line with the following line and for all fields obtained. It is successively repeated for all codes until a particular code is obtained from a series of fields in which the number of displacements found remains below a minimum value; this code is the required correct encryption code. <IMAGE>
